METAL-WINDOW CONSTRUCTION.

Application filed February 1, 1907. Serial No. 355,225.

Specification of Letters Patent.

Patented Nov. 23, ENE).

To all whom it may concern:

Be itknown that l, Fonsr'rn, a citizen of the United States, residing at Chicago. in the county of Cook and State of lllinois, have invented certain new and use ful Improvements in Metal-\Vindow Constructions. of which the following is a specification. I

This invention relates to metal window constructions and has reference more particulari y to improved means for producing a tight lit between a window sash and its guides which nevertheless permits a' free opening and closing movement of the sash without binding; and among the leading objects of the invention may he mentioned to provide means, preferably automatic, for adjusting and effecting-a tight tit of the sash in its own plane, for adjusting the sash in a direction transverse toits own plane, and for adjusting the sash in both directions together; to provide ineansfor releasing the window in any adjusted position, said means preferably opewiting in conjunction with the tit-adjusting means; to provide a construction of window guide facilitating the ready withdrawal and insertiono'f the sash and sash balance relatively to the window opening; to provide a cushioning means for the sash tending to soften jars imparted to the sash during operation and at the same time helping to exclude dust; and in other minor respects which ill hereinafter appear to improve in general upon window constructions of this type.

My invention will be readily understood when considered in connection with the acconipa nying drawings showing p 'acticalembodiinents of the several features in which the invention may be said to reside; and reierring to said drawings,

Figure l is a side elevati nal'vicw of a portion of a metal window sash and its guide, illustrating means adapted to automatically adjust the sash in itsown plane whereby to secure a tight lit at any position of the sash, and illustrating also a means for releasing the sash in any adjusted position; Fig. is a cross-sectional view on the line 2 --2 of Fig. 1; Fig. 3 is a vertical sectional view in a plane transverse to and through the sash stile. illustrating a form of my improve ments adapted to autonniticall v adjust the sash in a direction transverse thereto, and showing also a positive lock for the sash, the section being taken on the line S of Fig. a; Fig. 4; is a fragmentary elevational view of the structure illustrated in Fig. 3; Fig. 5 is a cross-sectional view on the line 5 of Fig. 3, looking downwardly; Fig.v 6 is a side elevational view of a portion of a sash and its guide, illustrating my novel two-piece. construction of sash guide facilitating the insertion of a window, a portion of its guide and the sash balance; Fig. 7 is a fragmentary elevational view, with the inner side of the hollow stile broken away, of an embodiment of my invention designed to etl'ect a simultaneous widthwise and cross wise adjustment of the sash relatively to its guides; Fig. 8 is a top plan view of Fi 7;

Fig. 9 is a cross-sectional view through a sash and stile and its guide, illustrating the application of independent means for effecting both a Widthwise and transverse adjustment of the sash relatively to its guide; Fig.

10 is an elevational view, partly broken away, showing a means for adjusting the and transversely of its ,own plane; Fig. 11 is a cross-sectional view on the line 1111 of Fig. 10; Fig. 12 is a sectional elevation, broken out, of one side of a double window casing, more particularly illustrating my novel two-piece construction of sash guide facilitating the insertion of the window, a portion of its guide and the sash balance; Fig. 13 is a cross-sectional view illustrating the channel guides shown in Fig. 11; Fig. 14 is a vertical sectional view, somewhat enlarged, on the line 1414: of Fig. 12; Fig. 15 is a cross-sectional view through the lower portion of the lower sash bar, showing one form of cushioning strip applied thereto; and Fig. 1G is a similar view showing a novel form of construction of cushioning strip and fastening means therefor.

Referring to the drawings, 1 may designate the stile, and 2 and 3 the uppe' and lower cross-bars, respectively, of a hollow sheet metal sash, and 4 may indicate the side post of the window opening, to which are suit-ably secured the strips 5 and G forming between them, with the faces of the wall 1-. the usual guide-grooveot the sash. In the construction of the sash, the ends of the up per and lower cross-bars 2 and 3 are inset and lapped under the ends of the stile and secured thereto as by rivets 7 so as to present flush inner and outer faces or sides through the sash. Slidably mounted within the channet-shaped stile 1 is a correspondingly chansash bodily simultaneously both widthwisenel-shaped member 8, the open side of which projects slightly beyond the open side ofthe member 1, and directly ei'igages the bottom Wall of the groove, preferably by inturned lips 9.

Secured to the transverse member of the channel 8 is-astrip having formed there .on a series of suitably spaced cam inclines 10, that are adapted for cooperation with bar 3 cured a tape 1s that extends upwardly to the drum of a suitable spring-actuated sash balance (not shown).

Pivotally mounted within the lower cross at is a bell-crank thumb lever 16,

one arm of which is adapted to engage the pro ection 12, while the other has a pinch-handle 17 extending through a slot 18 in the face of the bar and adapted to cooperate with the stationary pinch-handle '19 secured to the bar; so that by pressing the pinclrhandles 17 and 19 together, the short arm of the lever bears down uponthe projection l2 and thereby raises the sash relatively to the adjusting clia nnehstrip 8, thus,

throwing the sash relatively to its guides 7 so that the same may be freely moved up anddown. On the other hand, it will be observed that the normal upward pull on the. adjusting strip 8 by the sash balance tends, through the cooperating inclines 10 and 11 to adjust thesash in its own plane to a snug fit with the surface 42 constituting the abut-meats of the guide-grooves, thus preventing the introduction of dirt, 'mOiS- ture, cold air and thelike at such points. It will also be observed that the normal upward pull on the adjusting strip 8, acting through the projection 12 and operating lever l6, and counteracted by the weight of the sash, normally maintains the pinchhandles 17 and 19 in separated or operative position, ready to 'rele'aseithe sash. This same principle of operation is carried out in the mechanism illustrated in Figs. 3, 1 and 5,

adapted to effect R'lJI'fiDSVQlSQ adjustment of the side walls of the stile relatively to the guide-strips 5 and 6 forming the lateral members of the sashguide. In this form of the invention, there are secured to the inner sides of the side walls of the stile strips QOh-aving inclined portions 2O that v "engage and cooperate with transversely elastic yiel'ding'inclined or wedge-shaped mermbcrs 21" of an adjusting strip 21 lying he tween the strips 20. The upper end of the adjusting strip 21 is connected by a tape 1% t0 the sash balance, as already mentioned; and the action of the parts is such that the upward pull of the sash balance on-the ador the sash in the opposite direction,t rough the guide.

tive lock which may secure the sash in closed 22 that is secured to the inner transverse formed in its depending side walls a bearing for a short transversefspindle 2d, the ends of which spindle also have a bearing in inset portions 25 of the strips 20; but said spindle does not extend through the side walls of the stile itself. The spindle can be inserted in place by simply separating the sidewalls before insertion into the guidesufliciently to enable the insertion ofthe spindle into its bearings. The lower end portions of the sides of, the strip 211 are slotted to straddle the spindie 2&{550 that the'latter will not-interfere with the relativevertical sliding movement between the strip 21 and the strips 20; and the lower ends of the sides of strip 21 are united by a transverse channel strip 26 secured between them, which strip 26 extends a slight distanceinto the lower bar to form one member of-a releasing device, as more particularly hereinafter described. The bracket 22 also'has formed therein a pocket 27' lying in the plane of the sash and acconnnodating a sliding bolt or plunger 28, which plunger is normally pushed outwardly by a coil spring '29 to engage any one of a series of holes 30 that may be formed at suitablepoints in the guide-plate or strip his a releasing device for the oted on the spindle 24, the shorter arm of said lever extending and engaging a notch 28 in the under side of the plunger 28, while the longer arm of said lever extends into the bar 3 and is provided with a pinch tionary pinch-handle 84 secured to the'ba'r. The operation of the adjusting strip 21 in already described-in connection with Figsol and 2; while the compression of the pinchhandles'32 and 34: serves to both retract flocking bolt 28 and release the adjustt r-ip Ql to permit the free rising and movement of the sash.

tionadapted to efiect adjustment and justing strip 21, acting against the p position or in any desired open positiong. This mechanism includes a hollow castingwall of the stile as by rivets 23, and has.

or the stile and the strips 20 secured thereto plunger 28 I employ an elbow lever 31 pivlists. 7 8 and 9 I have shown a conthe cooperating inclines 21 22114120, acts to distend or spread apart the side walls elf-the stile into a tight lit with the sidewalls or? In this connection I have else illustrated a device in the nature of'e handle32 extending through a slot 33 in, the 2 j I race .of the bar and cooperating with a stathis form of the invention is similar to that a tight fit of the sashin its guide both in the plane of the sash and in a direction transverse thereto; Figs. 7 and Sshowing a single means for accomplishing both of these adustments; and Fig. .9 showing two cooperating means for this purpose. first to the construction disclosed in Figs. 7 and 8, designates the adjusting member in the form of a channel-strip, herein shown as having its closed side engaging the bottom of the sash-guide. From the side walls of the channel-strip 35 are cut and bent inwardly 'at intervals triangular-shaped tongues 35*, the characteristic feature of these members being that they are inclined both in and transversely to the plane of the sash; and ,36 designates a coiperating series of tongues ecured to the inner surfaces of the side 'walls of the stile, and correspondingly inclined both in and transversely to the plane of the sash. From this it will readily be seen that a downward movement of the sash relatively to the adjusting strip, by reason of the downwardly sliding movement of the tongues 36 overthe tongues 35 effects an outward thrust of the adjusting strip into the guide-groove in the plane of the sash by virtue of the inclination of the members 35 and 36 in the plane of the'sash, and also effects an outward thrust of the side walls of the stile into snug engagement with the guidestrips 5 and 6 by virtue of the inclination of the projeotionsin a di- -recti.on transverse to the plane of the sash and guide. The adjusting strip 35 is connected through tape 14 to a spring-actuated sash balance, as hereinabove suggested. In the construction disclosed in Fig. 9,.the adjustmen' pf the sash in its own plane is effected by the means disclosed in Figs. 1 and 2; and the lateral or transverse adjustment is effected by means consisting of a V-shaped strip 37 secured to the bottom wall of the guide-groove longitudinally thereof, its positively inclined walls being slidingly engaged by inturned flanges 38 on the adjusting strip 38;

Figs. 10 and ll illustrate a further modification, somewhat upon the principle of the construction shown in Figs. 7 and 8 in that it effects a snug fit of the sash against both the bottom and side walls of the guide,

groove; but. so far as the side fit con corned, operating to force the sash bodily toward one (preferably the outer) guidestrip. In this construction I employ an adjusting strip 39 in the form of a light'anglobar slidably engagin the bottom and inner sidewall of the guide-groove, as shownin Fig. 11; said strip having secured 'thereto at proper intervals obliquely and downwardly extending tongues ll) which, like the tongues described in Figs. 7 and S. are inclined both in and transversely to the plane of the stile 1; and overlying the tongues 40 Referring with car windows.

and cooperating therewith are correspondingly inclined tongues -11 that are bent in wardly from an inwardly turned oblique vertical extension 1 of the stile. From the foregoing construction it will be seen that the up 'ard pull of the adjusting strip 39 cooperating with the gravity of the sash, througl'i the tongues 14C- and all, acts to force the adjusting strip 39 into snug engagement with the bottom and inner side walls of the groove, and at. the same time acts to throw the stile bodily laterally against and into a sling fit with the outer guide-strip 5.

Figs. 6, 12 and 14; illustrate that. feature of my invention which relates to a novel construction of sash guide-strip facilitating the introduction of the sash and its balance in place in the window opening; this feature being more particularly, although not exclusively, designed for use in connection in Fig. 12 l have indicated at 42 a part of the fixed interior finish of the wall of a car above the window opening, 43 designating the usual shade roller secured thereto. 44 and 45 des gnate as entireties, a. pair of parallel channel guidestrips'secured to the post 16 of the window opening; 17 designating the usual sloping sill at the lower margin of the window opening. In accordance with my invention the sash-guide it is made in two parts; an upper part at and a lower part l-l". The horizontal joint a8 (Fig 12) at the meeting ends of the two parts is offset tnrough the inner side wall of the guide, as shown at 48, and from the metal forming the bottom or transverse wall of the strip all at its upper end is cut and pressed inwardly a tongue 45) having at its base an inward bulge 50 (Fig. 14) adapted to engage a wire loop 51 to which is connected the tape 52 of a sash balance 53 mounted in the sash (Fig. (3).

The tongue 49 overlies the lower end of the rear wall of the upper guide section 41', and is secured by screws 54: passed through said tongue and the underlying wall of the guide-member 44 and tapped into the post 16. It will be seen that by. reason of this construction the upper section ll can liist be secured in place, and the lower section i l, withthe sash balance tape properly connected thereto, can then, with the sash, be inserted directly in place from the inside of the car, and the screws 54.- secured in place. The sash can then be run up into the upper guide section, and the lower guide-section then suitably secured. This construction greatly facilitates the application of the sash-guides and the assembling of the sash and its balance inproper relation to said guides, especially in the case of car windows where the full height of the window opening its not available for the frontwise insertion of the sash andits guides.

in Figs. 15 and 16 I have illustrated, in

two forms, an improvement in means tor cushioningthe descent of the Sash onto the sill; the chief characteristic feature of this improvement residing in a construction which prevents the cushioning device from bein readily displaced laterally owing to the slant or inc nation at which the lower edge :5 the a Referring to 315, of the in sillv en 2. bar, and 5% the line of the b1. reby.

The enso .gageinent of the protubcrant and rentrant parts 59 and 57,- rcs'pectively, oiisetsand resists any sliding or squeezing ellect tending to laterally displace the cushioning strip when the window is dropped suddenly or hard upon the sill. In Fig. 16 is shown a modified construction designed to secure the same result. In this case a. plain metal strip 6'3, having threaded apertures is engaged by .one or more longitudinally bored studs 64L having smooth inner ends passing through holes in the cross-head 65 of the sash bar;

said strips being surrounded by a rubber sleeve or covering 66. The outer end of the stud64 is countersunk and receives a flatheaded screw 67, the threaded end of which is engaged and drawn tight by anut 68 having a countersunk face 69 adapted to receive and center the inner end of the stud 64; Strip 63 may also be of the concavo- 5.0 convex form, if desired, asdescribed in connection with Fig. 15.

It Will be observed that in those forms of adjusting devices wherein the adjusting strips are normally drawn upwardly as by a superposed sash balance, as in Figs. 1, 7 and 11, where these devices are applied on both sides of the sash, any cauting or tipping of the sash in its own plane is auto- I matically prevented ,by reason of the fact that the sash and its inclines act as an automatic equalizer of any inequalities of pull on the two sides of the sash'; it being evident thatif the pull on one side is stronger than on the other owing to a greater tension or 6-5 a difference in length of tape, the sash will y designate the lower end.
